Embodiment Construction

[0027] The present invention will be described in further detail below according to the drawings and embodiments.

[0028] refer to figure 1 , Figure 7 , Figure 8 According to the present invention, the oil-gas mixed transport pump includes a pump body 1 and a liquid collecting device 2 . The pump body 1 includes a pump casing 11 , a pump chamber 12 and an oil inlet chamber 13 . Among them, the pump casing 11 is composed of the framework of the pump body 1. The pump chamber 12 is arranged inside the pump casing 11 and is composed of an inner space separated by the pump casing 11. The pump chamber 12 is used as a container for the pump body. For the screw pump (not shown in the figure), the screw pump drives and transports the transported natural gas mixed with oil and gas located in the pump chamber 12 . An oil outlet 120 is provided in the pump cavity 12 , and the oil outlet 120 penetrates the pump casing 11 to externally connect to an oil and gas output device (not show...

Abstract

The invention discloses an oil-gas mixture transport pump, which comprises a pump body and a liquid collection device. The pump body includes a pump shell, and a pump cavity for accommodating a threaded rod in the pump shell. The middle section of the pump cavity is provided with an oil outlet running through the pump body. The pump shell is also internally provided with an oil inlet cavity, the two ends of which are communicated with the two ends of the pump cavity. The oil inlet cavity is provided with an oil inlet running through the pump body. The liquid collection device comprises a cylindrical liquid collection tank, an input pipe, and a liquid output device. The bottom of the liquid collection tank is connected to the liquid output device, and the pipe wall of the liquid collection tank is provided with an input port. The input pipe stretches into the input port and goes into the inside of the liquid collection tank. The pipe orifice of the input pipe is closely attached to the inner wall of the liquid collection tank. The pipe orifice center axis tilts downward and is tangent to the pipe orifice at the inner wall of the liquid collection tank. The oil-gas mixture transport pump provided in the invention performs gas-liquid separation of natural gas, sends liquid natural gas back to the peripheral space of the pump cavity, and realizes the gas-in-liquid state.

Description

technical field [0001] The invention relates to a pump, especially an oil-gas mixed transportation pump. Background technique [0002] As an important equipment for the extraction, collection and transportation of crude oil and natural gas, the oil and gas mixed transportation pump is widely used in the field of petroleum exploitation. It is a pump derived from the development of the petroleum industry in the past ten years. Corresponding research and product development have been invested in foreign countries; domestic theoretical research is almost blank, and corresponding products are not available. Traditional pumps can only transport liquids and cannot work normally when encountering gas in the medium. Therefore, it is very meaningful to design a pump that can realize multi-phase transportation of liquid and gas. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil-gas mixed transportation pump. [0004]...
